Lily is an avid gardener, so she decides to sell tomatoes at her local farmer's market. In order to test which tomato variety grows best in her yard, Lily plants 10 Brandywine and 10 Big Beef tomato plants. At the end of the season, Lily calculates the mean and a 95% confidence interval for yield for each tomato variety. The Brandywine variety had a mean yield of 21.33 pounds and the 95% confidence interval was (19.45,23.21), while the Big Beef variety had a mean yield of 24.50 pounds and the 95% confidence interval was (21.52,27.48). What do the confidence intervals suggest about the null hypothesis that the mean yield for Brandywine tomatoes is equal to the mean yield for Big Beef tomatoes? No conclusion about the difference in mean yield between the Brandywine and Big Beef tomatoes can be reached. Mean yield for Brandywine tomatoes is significantly different from mean yield for Big Beef tomatoes. Mean yield for Brandywine tomatoes is not significantly different from mean yield for Big Beef tomatoes. Mean yield for Brandywine tomatoes is equal to mean yield of Big Beef tomatoes
